Realbench massive score drop after 1803

[luckymatt42]

4770k on Asus Maximus VI Hero, 1603 bios, EVGA 1070 SC, 16Gb TridentX 2400.

Total of about 12 runs before the Win10 1803 update, average ~106k.
After 1803, roughly 10 runs average 97k.

After 1803, I used DDU to uninstall graphics drivers, updated to latest, still averaging 97k.

The only possibility I came up with was that Haswell was impacted harder by the Meltdown/Spectre patches (my bios is a couple years old, but the latest on the ASUS website for my board...so no firmware/bios spectre mitigations).

Any thoughts?

That are only benchmarks, what about real world perfomance in games?

I appreciate the question, as benchmarks don't always equate to real-world performance, but two things:
-It's not necessarily the absolute score, but the relative distance between scores before and after that really bothers me
-Second, it may sound a bit petty but I would like to increase my Realbench ranking (as a matter of personal pride if nothing else).

I have noticed a slowdown on all CPU intensive benchmarks, less so on GPU intensive ones.

Just wondering if other folks on older platforms like mine have noticed any particular cpu issues since 1803.
